Itching in the vulva is often caused by two possible causes: vulvodynia and vaginitis. Vulvodynia generally refers to inflammation that is confined to the vulva, and when you do a gynecological examination you can see redness, swelling or rash at the vulva, and sometimes you can see scratch marks due to severe itching. When treating vulvovaginitis, a topical lotion combined with antibiotics can be used to treat the affected area. The second condition is vaginitis. There are three most common types of vaginitis in clinical practice: bacterial vaginitis, trichomoniasis, and mycotic vaginitis. The clinical manifestations of these three types of vaginitis are different because the causative organisms are different. Therefore, before treating vaginitis, it is best to go to the hospital to get the secretion for laboratory test to know which type of vaginitis is present before treating the symptoms.
